Hi,
I think what your doing is really good, But not very practical when they start school. So perhaps you need to re-think the bedtime routine. I am speaking from personal experience as my husband use to work all day and return home at 10pm aswell.
Woohoo! good for you Wendy!!!
everyone is an individual, every household is different.
lives should be lived to suit the family and not the neighbours lol
keep up the good work and lots of luck with the home eding.
learning is life not school
